`CHAS. T. MILLER, OF PROVIDENCE, RHODE ISLAND.

ASH-SIFTER.

Specification forming part of Letters Patent No. 48,196, dated June 13,1865.

To all whom it may concern:

Be it known that I, GHAELEs T. MILLER, of Providence, in the county ofProvidence and State of Rhode Island, have invented a new and usefulImprovement in Coal and Ash Sifters 5 and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilledin the artto make and use the same, reference beinghad to the accompanying drawings, forming part of this specification, inwhich- Figure 1 is a side view ofa coal and ash sifter made according tomy invention, a portion of one side having been broken away to show partot' the interior. Fig. 2 is a vertical crosssection, taken on the line:c of Fig. l.

Similar letters of reference indicate correspondin g parts.

This invention has for its object to provide a coal and ash sfter whichmay be operated with ease, and in the use of which the operator will notbe annoyed by the rising of dust and tine ashes, noi` will these bepermitted to escape into the apartment in which the appara- A designatesa box with closed sides, Part of its cover is hinged, as seen at O, inorder to get access to a hopper, B, which overlies a swinging oroscillating sieve, G, which has va bottom ofwire-gauze. The sieve-frameis hung by means of links and chains a and b fastened to its ends, thechains b b being suspended from a cross-piece, f. The sieve-frame is notmade so wide' as the box in which it is placed, neither is it as long,so that it may freely oscillate within it without coming in contact withthe sides of the box. cisaninclined plane made within the box and fillingthe whole width thereof. Its highestpart is beneath the end of thesieve, and it reaches the bottom ofthe box near the side opening, F. Itspurpose is to direct the ashes and small matters which pass the sievetoward the opening F', where they. can be reached so as to beeasily'removed. The side opening, F,.is closed by a door, F, which mayslide in guides, or be constructed so as to operate in any otherconvenient way.

The right-hand end of the box is provided4 with a door, D, which may befastened by hooks or in any other convenient way. The inside of thisdoor has a shelf, g, placed a llttle below the level of the lower end ofthe sieve. Its use is to divert the coal which falls from the end of thesieve away from the door, so as not to accumulate in a pile at the lowerpart ofthe door.

The lower part of the door D is provided with an opening, which isclosed by a sliding gate, E, so that the coal which is gathered in thebox beneath theinclined plane c may be removed without the necessity ofopening the door `D.

Tothe lower part of the foot of the sieve is attached a rod, e, whichextends through one of the sides ofthe box A, and is attached to ahand-lever, d, outside of the box, the lower end of which hand-leverissecured to the side of the box by means ofa hinge, so that the lever maybe free to move toward and from the box.

In operating this apparatus the doors are to be closed, when the cindersor other matters to be sifted are put through the hinged cover C intothe hopper B, whence they pass onto the sieve G. The cover C is nowclosed, and

the sieve is gently oscillated by means of the lever d until the ashesand ue stuffhave passed through its bottom and the coarser stuft hasfallen over its end.

I claim as new and desire to secure by Letters Patent- The combinationand arrangement, in a coal and ash sitter, of the hopper B, vibratingsieve G, deecting-board g, inclined ash-board c, arranged reversely tothe sieve g, and doors D, E, and F, substantially as and for thepurposes described.
